To all whom it may concern:

Be it known that I, ARTHUR LA MoTTE, a

I citizen of the United States, residing at W ilmington, county of NewCastle, and State of Delaware, have invented a newand useful Improvementin Explosives and Process of Making the; Same, of which the following isa full, clear, and exact description.

This application is a continuation of an application filed by meDecember 7th, 1905,

' Serial No. 290,763.

.My invention has for its object the production of a new high explosiveof great and increased ex losive strength and a process Ri for making te same.

Ihavediscovered that an explosive consisting .of nitrate of ammonia, anitro-naphthalene, other than the mono-nitro-naphthalone, and anitro-toluene, other than the mono-nitro-toluene, is of great andincreased explosive strength. Preferably, I form this high ex losive ofseven parts of di-n-itronaphtha ene, vfive parts of tri-nitro-toluen'eand eighty-eight parts of nitrate of ammonia.

.To this is added two parts of pyrites.

I make this explosive in the following manner: I first melt thetri-nitro-toluene and add to that the di--nitro-na hthalene, makingahomogene'ous li uid. then add this liquid to the. nitrate o ammonia andallaw this admixture, after thorough incorporation, to'cool and harden.I then admix the pyrites with this admixture. Unless the yrites beadded, as above set forth, no benecial result will be obtained from theadditionof the-pyrites.

Having now fully described my invention, what I claim and desire toprotect by Letters Patent is:

40 ,1. .The process of forming a high explosive,

which consists in mixing with a SOllCl inorganic oxidizing agent anorganic nitro-compound or compounds, solid at ordinary temperature, in afluid condition, and, after said 45., mixture has hardened, adding thesulfid of a metal.

2. The process of forming a high explosive,"which consists in mixingwith nitrate of ammonia an organic nitro-compound or comound's, solid atordinary tem erature, in a uidcondition and, after sai mixture hashardened, adding the sulfid ot' a'metali 3. The process of forming ahigh explosive, which consists in mixing with a solid inorganicoxidizing agent an organic nitro- 5 compound or compounds, solidat-ordinary temperature, in a. fluid condition and, alter saidmixturehas hardened, adding pyrites.

4. The process of forming a high explosive, which consists in mixingwith nitrate of ammonia an organic nitro-compound or compounds, solid atordinary tern erature, in a uid condition and, after sai mixture hashardened, adding pyrites.-

5. The process of forming the high explosive described, which consistsin mixing together a nitro-naphthalene, and a nitrotoluene, both ofwhich are solid at ordinary temperatures, in fluid condition, withnitrate Y of ammonia; and, after the admixture has hardened, adding thesulfid of a metal.

6. The process of forming the high explosive described, which consistsin mixing together a nitro-naphthalene, and 9. nitrotoluene, both ofwhich are solid at ordinary temperatures, in fluid condition,withnitrate of ammonia; and, after the admixture has hardened, addingpyrites.

7. The process of forming the high explosive described, which consistsin mixing together a di-nitro-naphthalene, and a tri nitro-toluene, bothof which-are solid at ordinary temperatures, in fluid condition, withnitrateof ammonia; .and, after the admix ture has hardened, adding thesulfid of a metal.

8. The process of forming the high explosive described, which consistsin admixmg a di-nitro-naphthalene and a-tri-nitrotoluene, both in fluidcondition,'with nitrate of ammonia; and, after the admixture hashardened, adding pyrites.

'9. An explosive compound, composed-of a solid inorganic oxidizingagent, coated with an organic nitro compound or compounds, which aresolid at ordinary temperatures and having admixed therewith the sulfidof a metal uncoated with said nitrocompounds.

10. An explosive compound, composed of lcc nitrate of ammonia, coatedwith an organic nitro compound or compounds, which are solid at ordinarytemperatures and having admixed therewith the sulfid ofa metal, uncoatedwith said nitro compounds.

11. An explosivecompound, composed of a solid inorganic oxidizing agent,coated with an organic nitro compound or compounds which are solid at,ordinary temperatures and having admixed therewith pyrites, uncoatedwith the said nitro compounds.

12. An explosive compound, composedof nitrate of ammonia, coated with anorganic nitro compound or compounds, which are solid at ordinarytemperatures and having admixed therewith pyrites, uncoated with saidnitro compounds.

13. An explosive composed of nitrate of ammonia coated with an admixtureof a nitromaphthalene and a nitro-toluene which are solid at ordinarytemperatures and hav ing the sulfid of a metal, uncoated with the nitripcompounds, mechanically mixed there- Wlt t 14. An explosive composed ofnitrate of ammona coated with an admixture of a nitro-naphthalene and anitro-toluene" which are solid at ordinary" temperatures and havingpyrites, uncoated' with the nitro compound, mixed therewith.

' 15; An explosive composed of nitrate of ammonia coated with anadmixture of di- Intro-naphthalene and tri-nitro-toluene and having a'suliid of a metal, uncoated With the nitro compounds, mixed therewith.

16. An explosive composed of nitrate of ammonia coated with an admixtureof dinitro-naphthalene and trinitro-toluene and having pyrites, unooatedwith the nitro compounds, mixed therewith.

In testimony of which invention, I have hereunto set my hand, at Lee,Mass, on this 28th day of March, 1907 ARTHUR LA MOTTE Witnesses:
